This invention relates to newanduseful improvements in a valve, I One object of the invention is to provide a valve of the character described specially adapted to be incorporated into apipeline, or other conduit, and which may be actuated into two positions and. which, when in one position will close said line or conduit to pre- .j, vent the flow of fluid therethrough and when if, in the other position will not only open the conduit but will provide a substantially uniform, smooth conduit through the valve casing, forming a continuation ofthe line orcons duit, without obstructions, or pockets, to collect' foreign matter, or objects, in the fluid which, if collected, might injure the mecha nism or prevent the'properseating of the movable parts thereof. Another object 'of the invention is to prob vide a simple valve structure, which may be cheaply produced, which is precise and positive in its action and whose parts when seated in either open or closed'position will effec- PM tively prevent the leakage ofthe fluid past them.

With the above and other objects in view this invention has particular relation to cer tain novel features of construction, operation and arrangement of parts an example of 3% which is given in this specification and illustrated in the accompanying drawings wherein r Figure 1 shows a vertical sectional view of the mechanism taken longitudinally of the conduit into which the valve is incorporated, showing the valve in open position. i Figure 2 shows a similar view with the valve in position to close said line or conduit.

I Figure?) shows a transverse vertical sectional view,showing the conduit closed by the valve, and p i Figure 4 shows a transverse vertical sectional view, showing the conduit open through the valve casing. V a

Referring-now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures the numeral 1 designates, as a whole,

a casing, which includes the end caps, or 50' plates 2 and 3, preferably detachable therefrom. The end plate 2 is equipped with a suitable stuffing box designated generally by the numeral 4. A11 actuating rod 5 works through this stuifing box and has an annular rib 6 thereon located between the end plate and the gland 7, forming part of said stuffing box, said rib-permitting said rod 5' to turn but preventing its end wise movement.

The stuffing box, generally stated, may be line, or flow line may be connected, the con nections 10 forming continuations of the conduit through said line and theseconnections have oppositely disposed valve seats 11, 11, within the casing, and which are preferably detachable.

Within the casing are the oppositely disposed annular sleeves 12, 12 whose inside diameters are substantially equal to the inside'diameter of the connections 10 and. the

facing sides of these sleeves are sloping, or

diverge toward the p1ate3. Each sleeve 12 has the laterally extending Wings 13, 13 and the depending outwardly turned shoulder 14.

Oppositely working valves 16, 16, are provided which are movable into active position to seat against the seats 11, 11 to close the flow line or conduit and are also movable into inactive position to open said conduit, as will be more particularly hereinafter set out. Between the valves 16 there is an actuating nut 17 and the inner end of the rod 5 extends through said nut and has the threads 18 which have a threaded connection with said nut. The inner end of said nut has a sloping, or beveled face 19 and the nut is 7 formed with shoulders 20, 20 which are opposite and adapted to engage corresponding inwardly extending shoulders 21, 21 carried by the inner faces of the valves 16.

There is a wedge member 22, between the valves 16, which has a sloping face 23 re- I versely beveled with respect to, and adapted to co-operate with,the sloping 'face 19into which the inner end ofthe nut 17 is formed.

' 'The end 01": theyw'edge member 22, adjacent the nut 17 has a'deep socket 24 'into which the inner end .of the actuating rod 5 may workand'the other end of the memberi22I is formed with a ring 25 whose-opposite sides are outwardly tapered, or flared, forming substantially annularfiaces-QG, 26,2adaptedito r workegaihst-the opposingslopingtaoes J2,

A continued 7 valves apart and seat them securely against the corresponding seats 11- and thus securely .close the conduit or-fiow line.

supplemental conduit is provided to take its place between the valve seats 11 and form a continuous unobstructed passageway through thevalve casing without internal projections and with a-ll parts of the mechanism protected against injury from objects in the fluid flowing through said line and without internal cavities or pockets into which the offending. matter may collect.

We have illustrated and described one form of this mechanism, which we now believe to be a preferred form of the device but it is obvious that mechanical changes or adaptations may be made, without departing from the principle of the invention, if it be hereafter desired to do so, and we hereby reserve the right to make such mechanical changes or adaptations as may be compre hended within the scope of the appended claims. i 7
